[0069] Currently, as the performance of servers in data centers increases, the heat dissipation requirements for server chips and other components also increase.

[0070] Related technologies use cold plate liquid cooling servers to address server heat dissipation issues within data center computer rooms. However, the liquid cooling system in these cold plate liquid cooling servers can only dissipate heat from components with high heat generation, such as the server's chips.

[0084] In some embodiments, the cold source module 3 includes: a compressor 31, a condenser 32, a first fluorine pump 33 and an electronic expansion valve 34; the input end of the compressor 31 is connected to the output end of the second branch 19 and / or the output end of the fourth branch 24 through a refrigerant pipeline, the input end of the condenser 32 is connected to the output end of the compressor 31 through a refrigerant pipeline, the input end of the first fluorine pump 33 is connected to the output end of the condenser 32 through a refrigerant pipeline, and the output end of the first fluorine pump 33 is connected to the input end of the second branch 19 and / or the input end of the fourth branch 24 through a refrigerant pipeline; an electronic expansion valve 34 is provided between the fluorine pump 16 and the input end of the second branch 19 and / or the input end of the fourth branch 24, and the electronic expansion valve 34 is used to adjust the flow rate of the refrigerant.

[0085] Specifically, when the refrigerant in the refrigerant pipeline flows through the second branch 19 and the fourth branch 24, it absorbs heat in the server and the computer room to form low-pressure, low-temperature refrigerant vapor. The compressor 31 compresses the low-pressure, low-temperature refrigerant vapor into high-pressure hot steam.

The cooled refrigerant circulates back to the second branch 19 and the fourth branch 24 through the first fluorine pump 33, continues to absorb heat in the server and the computer room, and forms a closed loop.

[0088] Optional, such as Figure 7-Figure 9 As shown, the cold source module 3 also includes a radiator 38 and a second fluorine pump 39. The input end of the radiator 38 is connected to the output end of the fourth branch 24 through a refrigerant pipeline; the input end of the second fluorine pump 39 is connected to the output end of the radiator 38 through a refrigerant pipeline, and the output end of the second fluorine pump 39 is connected to the input end of the fourth branch 24; at this time, the fourth branch 24, the radiator 38 and the second fluorine pump 39 form a refrigerant circulation loop. The refrigerant passes through the fourth branch 24 in the second evaporator 21, absorbs heat from the coolant in the third branch 23, and flows to the radiator 38, where the heat is dissipated outside the machine room.

[0089] At the same time, the output end of the first fluorine pump 33 is connected to the input end of the second branch 19 through a refrigerant pipeline, and the input end of the compressor 31 is connected to the output end of the second branch 19 through a refrigerant pipeline. At this time, the second branch 19, the compressor 31, the condenser 32 and the first fluorine pump 33 constitute another refrigerant circulation loop. The refrigerant passes through the second branch 19 in the first evaporator 11, absorbs the heat of the coolant in the first branch 18, and flows to the condenser 32, and dissipates the heat outside the machine room in the condenser 32.

[0090] Optionally, the condenser 32 may be an evaporative condenser 32 or an air-cooled condenser 32 , and the radiator 38 may be a liquid-cooled radiator 38 .

[0091] In some embodiments, the cold source module 3 also includes a first one-way valve 35, a second one-way valve 36 and a third one-way valve 37; wherein, the input end of the first one-way valve 35 is connected to the output end of the compressor 31 through a refrigerant pipeline, and the output end of the first one-way valve 35 is connected to the input end of the condenser 32 through a refrigerant pipeline. The first one-way valve 35 can prevent the refrigerant from flowing back to the compressor 31 when the compressor 31 stops working, thereby avoiding damage to the compressor 31; the input end of the second one-way valve 36 is connected to the input end of the compressor 31 through a refrigerant pipeline, and the output end of the second one-way valve 36 is connected to the output end of the first one-way valve 35 through a refrigerant pipeline; the input end of the third one-way valve 37 is connected to the input end of the first fluorine pump 33 through a refrigerant pipeline, and the output end of the third one-way valve 37 is connected to the output end of the first fluorine pump 33 through a refrigerant pipeline.

At this time, the compressor 31 in the cold source module 3 works independently to provide sufficient cooling capacity to meet the cooling load requirements of the server and the computer room.

[0093] When the outdoor temperature is high all year round, for example, the data center is located in a tropical climate, the cold source module 3 is composed of a compressor 31 and a condenser 32. Figure 10-15 As shown, the cold source module 3 completely relies on the compressor 31 for cooling; or; Figure 16-Figure 18 As shown, the cold source module 3 is composed of a compressor 31, a condenser 32, a radiator 38 and a second fluorine pump 39. The cold source module 3 relies on the compressor 31 and the radiator 38 for cooling. In this way, the structure of the refrigeration system is more streamlined, the installation is more convenient, and it can provide sufficient cooling effect.

[0094] In another embodiment, if it is winter or the outdoor temperature is relatively low, the compressor 31 is turned off, the first fluorine pump 33 is turned on, the second one-way valve 36 is turned on, and the third one-way valve 37 is closed. At this time, the first fluorine pump 33 in the cold source module 3 operates independently, using the low temperature environment outside the machine room for cooling, and exchanging heat with the outdoor cold source through the circulating refrigerant to achieve a cooling effect and maintain low energy consumption.

[0095] In another embodiment, if it is the transition season between spring and summer or when the outdoor temperature is moderate, the compressor 31 is turned on, the first fluorine pump 33 is turned on, the second one-way valve 36 is closed, and the third one-way valve 37 is closed. At this time, the compressor 31 and the first fluorine pump 33 work at the same time, and the compressor 31 can operate at a lower frequency, which can achieve energy saving while realizing refrigeration.

[0096] In summary, the states of the compressor 31 and the first fluorine pump 33 in the cold source module 3 can be adjusted according to the change of the outdoor temperature to ensure the efficient operation and energy saving effect of the refrigeration system.

[0097] Optionally, the refrigeration system can be installed in an integral or split manner according to the actual situation of the machine room. When the integral installation is performed, except for the heat exchange coil and the liquid cooling cabinet 22 installed in the machine room 5, the rest of the parts are installed outside the machine room 5; when the split installation is performed, the condenser 32, the first fluorine pump 33, the radiator 38, and the second fluorine pump 39 are installed outside the machine room 5, and the rest of the parts are installed inside the machine room 5, for example Figure 19 、 Figure 20 shown.

[0098] In some embodiments, combined Figure 21 As shown, the refrigeration system further includes a controller 4, a first temperature sensor 41, a second temperature sensor 42 and a third temperature sensor 43; wherein the first temperature sensor 41 is used to detect the ambient temperature outside the computer room; the second temperature sensor 42 is used to detect the ambient temperature inside the computer room; and the third temperature sensor 43 is used to detect the temperature of the server;

[0099] The controller 4 is connected to the first temperature sensor 41, the second temperature sensor 42, and the third temperature sensor 43 respectively, receives the temperature data detected by the first temperature sensor 41, the second temperature sensor 42, and the third temperature sensor 43, and is respectively connected to the compressor 31, the first fluorine pump 33, the first one-way valve 35, the second one-way valve 36, the third one-way valve 37, and the pump mechanism to control the operation.

[0100] An embodiment of the present disclosure provides a cooling control method for a data center. The method can be applied to the aforementioned cooling system. The method can be executed by a controller 4 of the cooling system. The method includes:

[0101] When the air cooling module 1 and / or the liquid cooling module 2 are started, the ambient temperature outside the machine room is obtained through the first temperature sensor 41;

[0102] When the ambient temperature outside the machine room is greater than the first temperature threshold, the compressor 31 is controlled to be turned on and the first fluorine pump 33 is controlled to be turned off;

[0103] When the ambient temperature outside the machine room is less than or equal to the first temperature threshold and greater than the second temperature threshold, the compressor 31 and the first fluorine pump 33 are controlled to start;

[0104] When the ambient temperature outside the machine room is less than or equal to the second temperature threshold, the compressor 31 is controlled to be turned off, and the first fluorine pump 33 is controlled to be turned on.

[0105] In this embodiment, when the ambient temperature outside the machine room is greater than the first temperature threshold, that is, the ambient temperature outside the machine room is high, the first fluorine pump 33 cannot provide sufficient cooling capacity. The fluorine pump 16 is turned off by the controller 4 of the refrigeration system, and the compressor 31 is turned on. The refrigeration is completely dependent on the compressor 31 to provide sufficient cooling effect.

[0106] When the ambient temperature outside the machine room is between the first temperature threshold and the second temperature threshold, that is, the ambient temperature outside the machine room is moderate, the compressor 31 and the first fluorine pump 33 are controlled to be turned on, so that the compressor 31 and the first fluorine pump 33 work simultaneously. The compressor 31 runs at a lower frequency, and the first fluorine pump 33 assists in cooling. This can save energy while ensuring the cooling effect, thereby achieving a higher energy efficiency ratio.

[0107] When the temperature outside the machine room is lower than the second temperature threshold, that is, the ambient temperature outside the machine room is low, the compressor 31 is controlled to be turned off, and the first fluorine pump 33 is controlled to be turned on, so that the first fluorine pump 33 runs alone to utilize the low temperature environment outdoors for efficient cooling and save energy consumption.

[0108] Optionally, the above method further includes:

[0109] The ambient temperature in the computer room is obtained through the second temperature sensor 42, and the temperature of the server is obtained through the third temperature sensor 43;

[0110] When the ambient temperature in the equipment room is greater than the third temperature threshold, the air cooling module 1 is controlled to start;

[0111] When the temperature of the server is greater than a fourth temperature threshold, the liquid cooling module 2 is controlled to start.

[0112] In this embodiment, the air cooling module 1 and the liquid cooling module 2 can be started or shut down by controlling the pump mechanism in the air cooling module 1 and the liquid cooling module 2. Whether to start the air cooling module 1 and the liquid cooling module 2 is determined based on the obtained temperature in the computer room and the temperature of the server. This can achieve precise control of the air cooling module 1 and the liquid cooling module 2 and maintain a stable heat dissipation effect in the data center.
